Patients use Nordic Walking to alleviate their problems by regularly engaging in physical activity at a heart rate of 110-140 beats per minute. Nordic Walking is a suitable activity for any weather conditions, including rain, wind, and snow. By engaging in this activity, the immune system and its functions improve, and the body begins to adapt to changes in weather, equipping itself against getting colds. The immune system’s function is closely related to overall mental well-being, so regular physical activity will strengthen immunity in any case.
